Gary,
Glad to see your getting the cat back together,hopefully the damage is minimal,might want to ask Lance(Oster),I still think he's the best kept secret in Havasu...
Or,
There is a guy here in Albuquerque,doing bunches of EFI marine stuff,if your interested,I can get his number for you...

If you're are going to dyno it, I would highly recommend Larry's Engine in Tucson. Anything high performance I deal with goes to Peto's shop. He's done a few motor re-mapping jobs for me and I have nothing but good things to say. He's also done some big hp carb blower motors for me. I also know Pfaff can do it, they seem to have a loyal following, I haven't worked with them personally. If you have the o2 sensor welded in your exhaust, Pfaff could do at the lake for you. I not sure but Id be willing to bet Dustin at Whipple could program it as well.

I do have the bung for the o2 sensor, want to have the motor freshened and remapped as it always been a little rich on bottom. Looking for someone local that can do both. If I were closer to Peto that would be my first choice.

Nice stuff but without an engine dyno and the key, you cant change the program.

Hi Blown Lavey,
No need for an engine dyno or a key, you can tune any MEFI controller with the MEFIburn software. Dyno's get you close, but the correct way to tune it is in your boat, with a wide band O2 hooked up and monitoring your air/fuel ratios under all operating conditions. You would be surprised at how much difference there is between an engine perfectly tuned on an engine dyno and then how it performs once installed in the boat.

Gordon from Pfaff's and I may be out in Havasu in the next week or 2, give me a shout if you need help or want more information.
